| 摘 要： | 高温高压下温度梯度法合成宝石级金刚石时，合成周期较长。单晶种合成效率低下，通过多晶种法可以直接有效地提高合成效率，因此文章对多晶种生长宝石级金刚石进行了研究，在高温高压条件下成功实现了多颗粒2-3mm级金刚石单晶的合成，优质单晶的平均增重速度最快可达1．88mg／h。

| Abstract: | The synthesis of gem diamond crystal needs a long time by temperature gradient method under high temperature and high pressure.It is inefficient to grow one single crystal with a seed at a time.It will improve the synthesis efficiency to take more crystals as seeds in a reaction cell.Therefore,this paper investigates the synthesis of multi-particle large single crystals using multi-seed in a reaction cell.Multi-particle diamond crystals with 2~3mm in size were synthesized successfully in a reaction cell,and... |
